Download or read book Applications of LC MS in Environmental Chemistry written by Damia Barcelo and published by Elsevier. This book was released on 1996-03-21 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Looking at the literature available, it is clear that there is a need for a book on LC-MS applications in environmental analysis. This book endeavours to answer the following questions: What interface to use to solve "my detection problem"? Can I obtain enough sensitivity for the confirmation of my compound in real-world environmental samples? Is there enough structural information?The present book aims to provide a critical evaluation of LC-MS in environmental chemistry and it is structured in different areas. Apart from an introductory section with fundamental aspects, application areas using the most relevant interfacing systems (PB, TSP, ES) for the characterization of environmental compounds are included. In this sense, applications are discussed on the characterization of the most relevant compounds of environmental interest such as pesticides, detergents, dyes, polar metabolites, waste streams, organotin compounds and marine toxins with comparison between different interfacing systems. Finally, new methods and strategies in LC-MS, e.g. the use of capillary electrophoresis, MS together with on-line post-column systems in LC-MS are also shown.By the nature of its content and written as it is by experienced practitioners, the book is intended to serve as a practical reference for analytical chemists who need to use LC-MS in environmental studies. Each chapter includes sufficient references to the literature to serve as a valuable starting point and also contains detailed investigations. The broad spectrum of the book and its application to environmental priority compounds makes it unique in many ways.

Download or read book Mass Spectrometry written by James M. Thompson and published by CRC Press. This book was released on 2017-12-22 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that there are about 10 million organic chemicals known, and about 100,000 new organic compounds are produced each year. Some of these new chemicals are made in the laboratory and some are isolated from natural products. The structural determination of these compounds is the job of the chemist. There are several instrumental techniques used to determine the structures of organic compounds. These include NMR, UV/visible, infrared spectroscopy, mass spectrometry, and X-ray crystallography. Of all the instrumental techniques listed, infrared spectroscopy and mass spectrometry are the two most popular techniques, mainly because they tend to be less expensive and give us the most structural information. This book is an introductory text designed to acquaint undergraduate and graduate students with the basic theory and interpretative techniques of mass spectrometry. Much of the material in this text has been used over a period of several years for teaching courses in materials characterization and chemical analysis. It presents the mass spectra of the major classes of organic compounds and correlates the fragmentation pattern of each spectrum with the structural features of the compound it represents. This has been done for hydrocarbons, organic acids, ketones, aldehydes, esters, anhydrides, phenols, amines, and amides. The text discusses the origin of the fragments, techniques, innovations, and applications in mass spectrometry. It is interspersed with many illustrations, examples, an adequate but not overwhelming bibliography, and problems for students. It will serve as a lecture text for a one-semester course in mass spectrometry or can be used to teach the mass spectra portion of a broader course in material characterization and chemical analysis.
